IMPROVEMENT IN ACRN PLANTERS.

Specification forming part of Letters Patent No. 146,343, dated January13, 1S74; applicationiled October 15, 1873.

To all whom it may concern:

Be it known that I, J oHN KELLY, of Troy, in the county of Miami andState of Ohio, have invented an Improvement in Corn-Planters, of whichthe following is a specication:

The nature of this invention relates to an improvement in the droppingmechanism of y two-horse corn-planters, having for its object toproduce, by the movement of a hand-lever, a coincident and positivemovement of the rotary dropper-plate in each seed-box, and tov insurethe dropping of each charge of seed.

The invention consists in the peculiar mechu anism for operating thedropper-plates, as

more fully hereinafter set forth.

Figure l is a perspective view ot' my improved corn-planter, looking atit from behind. Fig. 2 is a plan of the under side of thedropping-plates and their covering-plates as removed from the mainframe. Fig. 3 is a sectional plan of a dropper box and plate.

` Fig. 4 is a cross-section of the brush at x x in Fig. 3.

Like letters refer to figures. y

In the drawing, A represen ts the main frame like parts in the several'1 v transverselyT mounted on the metallic furrowopeners B, with aseed-spout, C, leading to each from the rear corners of the frame. D isa seed-box at each end of the frame, closed "at the bottom by a metalplate, with a circular dropper-plate, E, pivoted on a stud, a, its rearpart rotating through a slot in the rear wall of the box. `Eachdropper-plate has a bevelgear, b, near the periphery, underneath,

' with which meshes a pinion, c, at either end of a shaft, F,transversely journaled in the frame, so that motion being given onedropper 1 thef shaft will impart it to the other. Above each dropper inthe box is a seed-plate, D', slotted to allow the corn to pass down tothe dropper-plate E,'and iill the cells 6, cut in the ,y same near itsperiphery. A brush, 7c, is secured in each box, through a hole in theplate D', just before the grain issues from the box,

to sweep oft any surplus corn that might otherwise clog` the plate. Onthe periphery of 'each dropper-plate will be noticed a series of end,which serves as a stop when it enters a notch, f, in the dropper-plate.To the extremities of the bar Gr are pivoted the outer ends of twosegments, G', Whose inner ends are pivoted to the lower ends of thestuds a, which carry the dropp'enplates. The outer edges of thesesegments carry two short posts, one ateach segment, to which is pivoteda pawl, j, which engages with the ratchet formed by the inclined planesg on the dropper-plates, and rotates the dropper-plate when the b ar ismoved in one direction, but slides back when the bar is moved in theopposite direction. The pawls, stop-notches, and ratchets of the twoplates are disposed in opposite directions, so that the bar G, beingreciprocated, moves one plate by its pawl, and said plate, through theshaft F and pinions b b, movest-he other plate, bringing a cell full ofcorn over the opening in the bottom plate, whence it falls through thespout to the ground. A reverse movement of the bar G rotates the otherplate, and, through the gearing described, it rotates the opposite one,causing both plates to drop'their seed simultaneously, at a singlemovement of the lever which actuates the bar G, and with ease andcertainty. L i y g '4 To compel each cell. to empty itself of any seedwhich may have wedged therein, a star wheel, H, is so pivoted behindeach dropperbox that one of its arms will always project into the slotthat comes under it, and thus force out the corn. i

What I claim as my invention, and desire to secure by Letters Patent,is-u 1. In a corn-planter, the combination of the rotary dropping-platesE, the intermediate shaft F, with bent gears c, and the reciprocatl ing'bar Gr, With its segments G G', all e011-- piuions e c, and providedwith the stopmotehe strueted and operating substantially as set fandperipheral ratohets g, the reciprocating forth. bar G, provided with thestops z' i, segments 2. The combination, with the frame A, fur- G G',and pawls jj, substantially as and for rori opener B, and seedspouts CC, of the the purpose set forth.

seed-boxes D D, each provided with a slotted JOHN KELLY. seed-plete, D',a bottom plate, and the rotary Vit-nessesz. dropper-plateE pivotedthereto, the said plates C. C. WEILAND,

E being geared together by the shaft F and L. H. THOMPSON.
